As we know that this number is a valid input of deg2km, we may try the following: deg2km distance 1 Does that work? If you get some output here that is the row number of the rows of N for which the waypoint could not be found. . Below are my coding and the data stored in excel. It would also have helped you to understand your first problem better. In that case, it's probably easiest to just run this at the command line: You want to take the index P i and grab the next 10 elements after that point, then put them into a row in M. I was writing a matlab prog. I don't fully understand what you are trying to do here, but I can tell you how to examine the issue.

May it be possible that there are waypoint ids defined that do not have a corresponding waypoint? In other words, M has to be a stacked product of P. We now know that we may pass a column vector to deg2km without further problems. With an error in a loop, however, it could be many iterations before you actually hit the parameter combination that will cause the error. Sheet 1 display the coordinate on each waypoint, Sheet 2 display the connection of the waypoints. Then we should try to understand what causes that input. This system is to generate the distance using two points of coordinates.

However, at the last part of the code it gives the error: Index Exceeds Matrix Dimensions. Do that as long as you need until you understood what is causing the problem. If it works, however, let's do deg2km distance 1:20 What about this one? Now there are only two things left: It is a specific entry in distance that causes trouble or the format of distance is not a column vector. The start variable are 0. However, I can't seem to get rid of the error. Then your code loops through each entry in that cell array, extracting it with urls{i} to get a character vector.

The reason why I bring the matlab 'sum' function is that my code's problem happens when assigning the value of the sum of the elements of a 1X7 bits vector by a 16X7 bits matrix to find the hamming distance between each of the 16 rows of the matrix and the single 1X7 vector, so that i will have 16 values for the hamming distance. Just differentiating names by their case is potentially faulty. Hopefully someone can help me with this! Reduce the data step by step and see where the error is happening. Thus, we are not missing further arguments. Either you give the wrong input or deg2km is faulty.

You could also try to narrow the problem further down: deg2km distance 1:10 If that works, we know the problem is located at an entry in distance 11:20. What I was doing with you in the comments was to try to do exactly that process. If this line contains an error, you will have to find a way to tackle that problem down to its root before being able to solve it. So the logical thing to do would be to make 'noise' bigger or P i smaller. That kind of strategy can be applied to almost all problems you might encounter. Of course you would have to run that command for N :,2 as well. This works fine for the first several iterations where P is picking out relatively small indices.

The problem is in saving or storing or assigning these values. Usually, that is something you should be able to do on your own. Is during conversion from degree to km. If yes, we look further deg2km distance 1:2 Does that work? But then you try to take the last character of row 24 of that character vector with your 24, end and that character vector does not have 24 rows. So, let's get into an example: You notice there is a problem in the statement deg2km distance There are only two things here that could go wrong. With any kind of error, it's often easiest to set a breakpoint at the line the error occurs.

However, some of the elements of P are picking out array elements near the end of noise , so there aren't 10 elements after those points to grab. Finally, you can write your selection in the distance function using the :-operator in a more compact way, as I have done above. Edit 1: I feel the need to give a few advices on usual bug tracking strategies. Thus, we have to understand what the problem with your input is. So to fix this error you need to replace the +10 with something else. If I recall correctly, the obsolete routine textread will return a cell array of character vectors when you use the %s format that you used. After that, fixing the problem usually is only a matter of seconds.

You can use min diff P to see the minimum distance between consecutive indices in P , or min abs P-length noise to see how close the last element in P is to the end of noise , or maybe you could just loop to length P -1 or length P -2 , avoiding the last few large indices in P. What you really want to do is to find the corresponding row in the waypoints columns that matches to the waypoint id in start or end, respectively. How could you help me to solve it? I was told not to index so far into P, but i have no idea how to do that. If that does not work, look into distance 3:20. Waypoints Latitude Longitude 1 11001 1. .
